“…This paper features a specially coated yellow surface that changes to dark blue upon contact with moisture. Water-sensitive paper has been employed in the agricultural domain to ascertain spray droplet size and distribution on plants [10], [11], [12], [13]. By positioning the paper on plant leaves during the spraying process, researchers can observe the staining of sprayed particles on the paper surface, which immediately shifts from yellow to blue based on droplet distribution.…”

Conducting ablution constitutes a prerequisite for Muslims prior to engaging in prayer. This ritualistic practice involves the cleansing and wiping of specific body parts, including the hands, face, arms up to the elbows, head, and feet. Ensuring comprehensive water coverage of the aforementioned areas is a crucial criterion during ablution. However, excessive water consumption often occurs when Muslims perform ablution to achieve full coverage. Consequently, a more ecologically sustainable approach to ablution is necessary to minimize water wastage. A proposed water mist spray device aims to optimize water usage while adhering to the Islamic jurisprudence requirements of complete water coverage on ablution parts.To assess water coverage using the mist spray, an evenness distribution profile is employed through atomized mist colorization on paper and thermal imaging of ablution parts. An appropriate spray nozzle is chosen based on an analysis of spray distribution and coverage patterns on the target surface, utilizing image processing techniques. The proposed methodology involves mixing water with red watercolour and manually pumping it through the selected nozzle using an off-the-shelf water sprayer, thereby atomizing the coloured water to stain white paper. Subsequently, the paper is converted into a digital image and analysed using ImageJ software to determine the mist spray coverage percentage, spatial spread at various distances, and the extraction of stain and droplet sizes. This technique is applied to different types and sizes of spraynozzles to identify the most suitable nozzle for the prototype.The findings demonstrate that nozzles with smaller exit holes and higher water pressure yield more extensive spray coverage on the target surface. Upon selecting the appropriate nozzle, a Portable Ablution Mist Spray Device prototype is employed to evaluate water coverage for the ablution body parts. Thermal images of the ablution parts are captured before and after the ritual, with the temperature differences being analysed. The thermal images reveal a comprehensive and uniform spray distribution on the ablution body parts, accompanied by a temperature difference ranging from 0.9°C to 3.8°C among various participants.

“…In previous studies, artificial collectors were used for the spray quality evaluation. An example of artificial collectors is water-sensitive paper (WSP), which was used extensively for droplet detection, because of its visual appeal. , The coverage, density, and deposition of pesticide droplets on WSP were measured using Deposit Scan . However, the use of the WSP has some limitations.…”

The current methods of pesticide application quality evaluation have many limitations, including their inability to measure coverage and deposition simultaneously. Therefore, a spray quality evaluation method based on disodium 4,4′-bis(2sulfostyryl) biphenyl (CBS-X) was developed in this study. This method does not require artificial collectors; instead, spray targets can be directly used for detection and coverage and deposition can be determined through image segmentation and target elution, respectively. The stability and accuracy of CBS-X were tested. Results showed that neither light nor storage influenced the coverage and deposition of CBS-X. The difference in coverage between this method and the water-sensitive paper (WSP) method was no more than 15%, and the difference in deposition between this method and the filter paper method was no more than 20%. Overall, the CBS-X-based method is not affected by environmental conditions and can be applied to inform the better pesticide application strategies.
